Abstract

Thirteen (13) oxazolone derivatives were synthesized and the photochemical behavior of one of them was analyzed for solvent polarity when submitted to irradiation in 350 nm. When acetonitrile is used as solvent, photodegradation is faster when compared with n-hexane. The electronic spectra in acetonitrile showed an isosbestic point in 419 nm, indicating that only two species co-exist in solution. The addition of a second solvent destroyed this behavior. The others solvents did not show an isosbestic point.
